Following through the pvfs2-cp.c example, it calls PVFS_sys_create. This function invokes the state machine found in src/client/sysint/sys-create.sm. This state machine sends a "create" request to the server, which in turn stores the metadata. Look in src/server/create.sm to see the server side of this processing. It stores information in both the dspace and keyval databases.

Thanks!
